VEHICLE-TIRE,

Specification of Letters Patent.

Application led October 14, 1910. ASerial No. 587,030. v

To all whom it may concern: V

Be it known that I, JOHN B. F IsoHnR, a

citizen of the United States, residing at object to provide an improved construction ofA resilient case tube or. tire which shall be simple, easy riding and durable, also readily accessible for repairs.

In the accompanying drawings: Figure 1 is a sectional view of the tire, showing a portion of the length thereof; Fig. 2,. a transverse section takenon the line 2 2 of Fig. 1; Fig. 3, a transverse section taken on the line 4 4 of Fig. l; and Fig. 4', a sec tional view taken on the line 5-5 of Fig. 1.

According' to my improved construction, the case tube or tire is formed with a. plurality or series of cavities, preferably rounded or spherical in shape, located within the tube around the circumference and separated by intermediate walls or spacers a2. The tube containing these cavities may' be constructed by taking a plurality of layers (5*, of fabric and rubberapplied to' a mold or form -to give the desired corrugated or rounded shape for the cavities. In the depressions between the corrugations are located the triangular or crescent shaped pieces a5, of what is known as cushion stock, which may be inclosed in a covering of several layers of fabric'and rubber, and over all additional layers a, of fabric and rubber are `then applied, making a substantially smooth external appearance with the two lips or flanges a', a, at the inner periphery. The exterior of the tire or casing a is then finished by adding suiiicient cushion stock and other material to form the wearing surface or tread of the tire. As shown in Figs.

- 2 and 3, this tube is of the split clencher type, the anges a, a being held and clamped together by the rim c of the wheel.. lVithin the tube the spherical cavi-ties are completed by inserting the spacers a2 which may be formed of cushion stock andhave recesses a3 open toward the inner periphery. These spacers or walls, are placed transversely ofthe tube, and secured at the points of depression of the corruga-tions of the. in-

ner tube with which they form. complete rounded 'or spherical cavities spaced apart throughout the tube.

The resilient crescent shaped pieces a5 which are formed of rubber cushion stock, constitute substantially an extension of the resilient transverse walls or spacing'pieces L2 into-the fabric in the inner portion of the tube 'so that whenever the tire engages an l obstruction at this point, the pressure is transmitted through the yielding and resilient crescent shaped piece to the upper .part of the ball and also through the spacing piecesto the sides and lower portion of the ball givinlg a more uniform pressure throughout.

Resilient or rubber balls b may, ifdesired, be inserted in the spherical cavities where they will be securely held by the walls of the spacing pieces.

In operation', to remove orintroduce a ball, the casing will bedetached for a convenient portion of its length and the flanges a and lower portions of4 the spacers a2 will be spread apart to the extent required. After a ball has been thus introduced and the casing parts released, the ball will be portion of the tire is affected. Indeed under ordinary circumstances the tire will not be put out' of commission and may be used either with or without the resilient balls 1ocated in the cavities. l

It will be noted that with my construction there is no special internal pressure upon the casing as in the case of an: inner tube or ordinary single tube tire and, therefore, the danger of blow outs is avoided.

lHaving now described my invention, what I claim as new and desire to secure by Let- 1. A resilient vehicle tire comprising a' case tube having 1ts1nner portion formed- 2. A resilient vehicle |tire comprisingJ a case tube having its inner portion formed with c'orrugations, crescent shaped pieces of A yielding rubber material lncased within the fabric at the depression points of the corrugations, and spacing pieces constituting transverse Walls inside the tube opposite the crescent shaped pieces,

thereby forming 5 cavities spaced apart throughout the tire.

3. A resilient v ehicle ltire comprising a case tube formed with corrugations upon its inner portion and split at its inner periphery,

resilient Walls closing the interior 10 of the tube at the depression points to form a. seriesof rounded cavities spaced apart7 and resilient 4. A resilient v' balls located in said cavities.

ehicle tire comprising a case tube formed with corrugat-ions upon its inner portion and split at its inner periph ery, resilient Walls having recesses open at the inner side and forming with the corrugations a series of rounded cavities, and resilient balls located inl said cavities.

ln Witness whereof, I have hereunto subi scribed my naine in the presence oit' tWo Witnesses.
